Pradeep Rawat passes away

Actor Pradeep Rawat Death News Blood Cancer: Actor Pradeep Rawat, known for his roles in the films "Ghajini" and "Lagaan," died at a hospital in Bhiwandi on Tuesday evening. He was 74 years old and had been battling blood cancer for the past five years. His business manager, Siddharth Tiwari, confirmed this. According to him, Pradeep Rawat had previously recovered from the disease, but the cancer returned a few months ago. He had been hospitalized for the past few months, and his condition had worsened in the past few days.

According to the health information website Cleveland Clinic, blood cancer is a serious disease that affects the production and function of blood cells in the body. Around 1.2 million people worldwide are affected by blood cancer each year. Most cases begin in the bone marrow. The bone marrow is the soft, spongy cavity within bones where stem cells are produced. These stem cells then develop into red blood cells, white blood cells, and platelets.

Red blood cells carry oxygen to different parts of the body. White blood cells fight infection, while platelets help stop bleeding. Blood cancer disrupts the body's normal process of blood cell production. Abnormal cancer cells multiply rapidly and begin to replace normal blood cells. These abnormal cells can no longer perform the same functions as normal blood cells.

How many types of blood cancer are there?

There are three main types of blood cancer. The first is leukemia, which usually begins in the bone marrow. In this, abnormal and often immature white blood cells begin to grow rapidly and can spread to the bloodstream. The second is lymphoma, which affects the body's lymphatic system. It begins in white blood cells called lymphocytes. The two main types are Hodgkin lymphoma and non-Hodgkin lymphoma.

The third is myeloma, which begins in the bone marrow and affects plasma cells. Multiple myeloma is the most common type. There are also rarer blood cancers, such as myeloproliferative neoplasms and myelodysplastic syndromes.

What are the symptoms of blood cancer?

Symptoms of blood cancer can vary depending on the type. Common symptoms include persistent fatigue, shortness of breath, swollen lymph nodes, and frequent infections. Bone or joint pain, excessive night sweats, enlarged liver or spleen, persistent fever, and unexplained weight loss may also be signs.

Easy bruising or unusual bleeding are also signs to look out for. Small red spots or purple patches may appear on the skin. However, these symptoms can also occur in other diseases. Therefore, blood cancer cannot be diagnosed based on these symptoms alone. If the problem persists for several weeks, it is important to consult a doctor.

Why does blood cancer occur?

Blood cancer can begin when changes, called mutations, occur in the DNA of blood cells. DNA tells cells when to grow, divide, and die. When DNA malfunctions occur, abnormal blood cells begin to multiply rapidly. They eventually outnumber normal cells, and the bone marrow is unable to produce enough healthy blood cells.

The risk of blood cancer may increase with age. Some blood cancers are more common in men. Smoking or exposure to secondhand smoke, long-term exposure to chemicals such as benzene and formaldehyde, previous chemotherapy or radiation therapy, and certain genetic conditions may increase the risk. Family history may also play a role in some types of blood cancer. However, most patients do not have a family history of blood cancer.

How is blood cancer diagnosed?

Doctors first assess the patient's symptoms and medical history. Blood tests may then be ordered. A complete blood count (CBC) measures the number of red blood cells, white blood cells, and platelets. Blood chemistry tests may also be performed. Imaging tests such as CT scans, MRIs, and PET scans may be performed if necessary. A bone marrow biopsy is also an important test, in which a sample of bone marrow is taken to examine normal and abnormal blood cells. Tests may also be performed to detect genetic changes that may contribute to cancer.

How is blood cancer treated?

Treatment depends on the type of cancer and the patient's condition. Chemotherapy is one of the main treatments for blood cancer. It uses drugs to kill cancer cells or stop their growth. Radiation therapy uses radiation to damage the DNA of abnormal cells. Immunotherapy helps the body's immune system fight cancer. Monoclonal antibody and CAR T-cell therapy are examples. Targeted therapy targets specific vulnerabilities or genetic changes in cancer cells.

Some patients may require a stem cell transplant. Autologous stem cell transplants involve preserving the patient's own healthy stem cells and then reinfusing them back into the body after high-dose chemotherapy. Allogeneic stem cell transplants involve obtaining healthy stem cells from a suitable donor.

Can blood cancer be cured?

In many cases, blood cancer is curable. In some patients, treatment aims to completely eliminate the cancer, while in others, the disease may be kept in long-term remission. Remission means that after treatment, the cancer shrinks so much that it cannot be detected by tests. According to US data, the five-year relative survival rate is approximately 67 percent for leukemia, 88.9 percent for Hodgkin's lymphoma, 74.3 percent for non-Hodgkin's lymphoma, and 61.1 percent for myeloma. However, these figures do not provide an accurate estimate of an individual's life expectancy. Many factors, including cancer type, stage, age, health, and response to treatment, affect the outcome.

There's no surefire way to completely prevent blood cancer. Even healthy people can develop it. However, abstaining from smoking and avoiding prolonged exposure to harmful chemicals can reduce some of the risk.
